Appliance Question 1: Refrigerator Too Cold

I got my first question, from Ken, about his refrigerator.

Ken asked:

I HAVE A JENN-AIRE SIDE BY SIDE THAT RECENTLY HAS BEEN GETTING EXCESSIVELY COLD IN THE FREEZER SECTION. NO MATTER HOW LOW I SET THE FREEZER, IT STILL WILL NOT COME ABOVE -10 DEGREES. I HAVE MADE SURE THAT THE FREEZER AIR VENTS ARE NOT BLOCKED, BUT THIS DOESN'T SEEM TO HELP. ANY SUGGESTIONS?? THANK YOU VERY MUCH AND HAPPY HOLIDAYS.

I answered him via e-mail, but I wanted to share my response with you:

If the thermostat (cold control) becomes unresponsive to change in the settings, you may have to replace the thermostat. The normal temperature in the fresh food section should be between 35 and 40 degrees F. The freezer section should be between 0 and -8 degrees F. Check the temperatures in the freezer and the fresh food sections before replacing the thermostat.

Ken, let me know if that worked for you. Remember to send your appliance questions to eric@erickleinert.com.
